123456 the easiest password, but I would still prefer "password" as password lol!
Well for tech savvy people like us, I doubt anyone of my kakis will use this kuku password right?

Quoted from HWZ:

Just days ago, it was revealed that thousands of Gmail, Hotmail, and Yahoo account IDs and passwords were leaked. A researcher has studied 10,000 of these accounts and passwords and concluded that the most commonly used password was 123456 and that a staggering 20% of users only used a password that was six characters long. Only 6% of users were savvy enough to use mixed alpha-numeric passwords.
